Be it known thatl, JQsEPHJ MEs TY- NAxyofPhiladelp-hia, in the State of Pennsy lyania, have invented certain new and .use- 5 m1.- l provements in Annealing Apparatus,

posi- The free end of the conduit 29 being connected with a source of compressed air, the presssure-regulater 32 is set to deliver the required pressure through the conduit 29 and inlet-pipe 28 into said receptacle above the level of said hydrocarbon, the particular ressure being indicated by the gage 33. l he stop-cock 52 being then opened, hydrocarbon and com-' pressed air are delivered together at any de sired pressure through the mixing-nozzle 45 within the localizer 46 in accordance with the rotary positionpf the valve-handle 54. Said mixture being delivered through the blast- I opening 22 in the furnace-chamber 19 is igscribed, not only. insures nitedtherein, and the products of combustion escape through the opening 23 at the top of said chamber. The preliminary heating of the compressed air preparatory to its mixture with the hydrocarbon; as above de complete combustion of the hydrocarbon, but also insures that such combustion shall begin in immediate I proximity to the burner 43, and the construction sipecified is such that the greatest heat is 20 and .conse uently 'the time mani ested in the'chamber 19 intermediate of the length of the hearth-slab 8, which suparticles introduced through the Work-inlet 20. Despite the fact that said chamber 19 is in communication with the atmosphere through said openings t: is found in practice that if wrought-irofifiivets are allowed to remain on said hearth Spin the region of concentrated heat for a few minutes they may be fused, and requiredto merely heat t em tbproper riveting temperature is reduced to the minimum.

The apparatusaforesaid is particularly ad- .vantageous for riveting in the field in that it not only enables the operator to heat the rivets to the reqbuirnd temperature in less time than is POSSl lBEVltll ordinary soft-coal'or charcoal furnaces, but also enables the operator to deliver a rivet at a higher temperature than is attainable by said ordinary means, so

that the rivet may e completely closed. and

headed in the structure while at a temperature mostfavorable for such deformation. Although' I-find it convenient to rovide the tortuous conduit within the Wal of the lo'calizer- 46 by bending wrought-iron pipe ins spiral coil and making said wall of iron seated in said inlet surroundingsaid burner .by connection with said frame; a localizer :as around said pipe, as shown in section in i-ig. IV, I dov not desire to limit myself to tlns particular method of construction. Moreover, I do not desire to otherwise limit myself to the precise arran ement and con struction of the a paratus ierein set forth, as it is. obvious t at various modifications may be made therein without departing from the essential features of my invention.

In an annealing apparatus, the combination with a frame comprising a table; of a casing of refractory material mounted upon said table and com rising a chamber for the articles to be annea ed, provided with a blastinlet, a Work-inlet and an outlet for products of combustion; a hydrocarbon-burner sup;

ported by said frame'in registry with said last-inlet and comprisinga mixing-nozzle; an oil-port in said nozzle; an air-port in said nozzle; a receptacle secured within said frame beneath said casing and arran ed to contain oil and compressed-Y air toget ier; a

localizer,-supported by said frame, surroundin said burner in registry (with said blastin ct and inclosing' a tortuous duct; conduits connecting said receptacle and 'saidnozzle,
